TO ALL WHOM IT MAY GONCERN:

Be it known that I, WILBUB F. CLARK, of Hagsmans Mills, in .the county of Montgomery, and State of New York, have invented a new and improved Cultivator; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable those skilled in the art to make and use the same referen e being had to the accompanying drawing, forming part of this specification, in whichi Figure 1 is a side sectional view of my invention taken in the line a: :v, 7/

Figure 2, a plan or top view of the some.

Similar letters of reference indicate corresponding parts.

This invention consists in a noveand improved construction of the cultivator, as hereinafter fully shuts and described, whereby the ground will be acted upon in the most efiicient manner, and the device be under the complete control of the driver. I 7 Wm,

The frame of the device consists of a stout plank, A, having itsniider side grooved transversely to form gains in which bars, BB, are fitted parallel with each other, and -firmly secured in position by one bo1t, a, vpassing through each and through the plank A. The bars 13 project in front of the plank A, and the bars B project behind it, as shown clearly in fig. '2, and in the front ends of th'e bars B the standards C of teeth I) ore secured, while the standards C of teeth I) are secured in the rear ends of the bars 13'. E is the draught-pole which is attached to the centre of theflplank A, in an inclined position relativelythercwith, as shown in fig. 1. The ends of the plank A are secured by journals-or pivots, z), in the front ends ofiron levers F F, the rear ends of which are connected by a. bar, G, having the drivers seat, H, attached to it in such a-manner that it-may be adjusted further forward or backward as required, and to these levers F F, aho'ut their centres, the wheels I I are attached. From the above description it will be seen that the driver counterpoises the machine, and that by throwing his body forward or backward at any time, may elevate the ploughs' out of the ground or keep them in the ground, as desired. To each lever there is attached a curved segment, J, which is perforated with holes, a, and similar perforated segments, K, are attached to the ends'of the plank A. By raising the plank A, and passing pins through the proper perforations in the segments 3' K, theteeth D D maybe kept above the surfaceof the ground, and drawn from place to place with the greatest facility: The device, it will be seen, may be con-- structed at every moderate cost, is extremely strong and durable, and will operate in the most e fiicient manner.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- 1. The plank A, grooved at its under side to receive the barsB B, which have the teeth standards 0 0' attached as shown, in combination with the levers F F, having the wheels I I attached, the plank pivoted between their front ends and the-'drivers seat H, secured to n cross-bar, G, attached to the rear ends of the levers, all arranged substantially as and for the purpose herein set forth.

2. I further claim the perforated segments J K, attached respectively to the lovers F F, and plank A, substantially as and for the purpose specified.
